When I was a teenager most of my peers tried smoking and did a bit of underage drinking. But it's a different story for today's teens.
A new study shows teenagers are much less likely to drink, take drugs and smoke than my generation ten years ago.
The reasons today's teens are better behaved than me and my friends is complicated, but it seems health messages are making more of an impact than they used to. A bit of teenage rebellion is part of growing up, but harmful chemicals don't have to play a part.
